In an image processing system according to an embodiment, a display unit simultaneously displays a predetermined number of parallax images. A parallax image generation control unit performs control such that a group of parallax images of point-of-view positions which are larger in number than the predetermined number is generated. A display control unit classifies the group of the parallax images into a first parallax image sub group including a set of parallax images whose point-of-view positions are discontinuous to each other and a second parallax image sub group including parallax images whose point-of-view positions are between the set of the parallax images, and performs control such that the display unit displays the first parallax image sub group and the second parallax image sub group while switching the first parallax image sub group and the second parallax image sub group at a predetermined switching speed.
